Glowing wake of youth

My daughter turns eighteen today,
The youngest of four.

I am feeling today my job is done,
They are all capable of closing the door.

I wish I had some wise parting words,
I don’t, I know they have more.

I brought them up best I could,
Now they leave me in awe.

I marvel at their independence,
And yet cringe at some choices they make.

They are important to all the people,
Leaving their world glowing in their wake.
